In case of swimming it's not desirable, because you'll be logged back in in the middle of a lake of example but since drowning now only gives asphyxiation damage it's not instant death anymore.
As for fighting , it just stops: an animal will simply despawn and a human will be logged out just like you (since it's doubtful you'll log back at the same second the fight is over with a draw being the result) - in fact in earlier words there have been reported cases when during faction on faction wars the loosing side would crash the server on purpose to save their fighters/bases.
